Been down the rabbit hole lately of UEFI Secure Boot issues, and decided to write an overview of how it works out-of-the-box in the excellent Debian-based Linux Mint LMDE 6.
Have mostly been researching this stuff as I was looking to replace GRUB entirely with systemd-boot on one of my systems. Will likely write a follow-up piece documenting that journey if I think it’d be interesting to some nerds out there.
Hard same. systemd-boot is about as tricky as, say, syslinux (which I used to use) to get working, which is itself far simpler to work with than GRUB ever was.
